The invention discloses a composite material combined type cross arm for a high-tension transmission line tower pole. The composite material combined type cross arm comprises two anti-bending composite insulating parts and two tensile composite insulating parts. Four end part armor clamps and four root part armor clamps are respectively arranged at the end parts and the root parts of the anti-bending composite insulating parts and the tensile composite insulating parts, wherein the end part armor clamps and the root part armor clamps, which are respectively arranged at the two ends of the anti-bending composite insulating parts are spliced; the end part armor clamps and the root part armor clamps, which are respectively arranged at the two ends of the tensile composite insulating parts are pressed; and an end part clamp connecting plate is used for fixedly connecting the four end part clamps through bolts to form the composite material combined type cross arm. The structure of the composite insulating parts is improved so that the self gravity of the composite cross arm is effectively reduced, the diameter of an electric gap circle between a wire and an iron tower is reduced, and the width of a passage and the tower height are reduced. The composite material combined type cross arm is simple in structure and fast to assemble and can be arrayed into tower shapes including a drum shape, an umbrella shape and the like, so that the occupied land is saved and the composite material combined type cross arm is good for popularization and application.

The invention discloses a wooden floor structure supporting device with a leveling function, comprising: a shock absorbing pad, a support plate and a base arranged from top to bottom; the shock absorbing pad is fixedly installed on the upper surface of the support plate, The support plate is fixedly connected to the base through a positioning mechanism and a leveling mechanism. By setting the leveling mechanism and adjusting the height of the support plate, the precise fine-tuning of the height of the wooden floor is realized, which ensures the flatness of the wooden floor laying; in addition, by setting the positioning mechanism, the support plate can be guaranteed to move in the vertical direction to prevent sideways and the support device has high mechanical strength, stable structure, and strong shock absorption performance; it is convenient for construction and improves construction efficiency.

The invention discloses a double-simple-support type anti-falling comb-shaped bridge expansion device. The device is characterized in that a comb plate A is arranged on an anti-falling steel plate, comb teeth of a comb plate B and comb teeth of the comb plate A are arranged on the anti-falling steel plate flat in a mutual insertion mode, and the anti-falling steel plate is supported by a base anchoring part A and a base anchoring part B provided with a stainless steel sliding plate through a simple support structure; a tooth root end plate of the comb plate A is fixedly connected with the anti-falling steel plate and the base anchoring part A; a tooth root end plate of the comb plate B is arranged on the stainless steel sliding plate through a leveling steel plate and fixedly connected with the leveling steel plate, the stainless steel sliding plate and the base anchoring part B. Compared with the prior art, the device has the advantages that comb teeth of the comb plate B and comb teeth of the comb plate A intersect and stressed together in a simple support mode, the winding degree of comb teeth is reduced greatly, the rigidity of comb teeth is improved by 100%, safety performance is improved, service life is prolonged, and the device is especially suitable for high-grade highway bridges, elevated bridges and ultralong flexible bridges.
